Abstract
Description
- This application claims the benefit of the filing date of French Patent Application Serial No. 1855159, filed Jun. 13, 2018, for “Female Nozzle of a Connection Enabling the Insertion of a Male Nozzle With a Reduced Force.”
- This invention relates to a female nozzle of a connection, for example for fluid transport pipes.
- French Patent No. FR2883607 discloses a tubular connection consisting of a female and a male nozzle. The male nozzle is intended to be inserted coaxially into the connection end of the female nozzle. The female nozzle includes an O-ring located within an annular recess inside the main body forming the female nozzle. This gasket ensures the sealing of the connection when it is connected between two fluid transport pipes. The recess is formed by an internal shoulder of the female nozzle and by the circular section of a retaining ring inserted coaxially into the main body of the female nozzle. The annular recess and the O-ring are completely contained in a transverse plane, perpendicular to the direction of insertion of the male nozzle.
- When the male nozzle is inserted into the female nozzle, the penetrating end of the male nozzle makes simultaneous contact with the O-ring on the whole periphery thereof. The axial insertion force that has to be applied to the male nozzle to compress the gasket and enable it to progress to its connection position is high, making the use of the connection uncomfortable.
- U.S. Patent Publication No. 2008/0217912 seeks to provide a solution to this problem. In this document, the annular recess in which the O-ring is positioned is not arranged in a transverse plane, i.e., perpendicular to the direction of insertion of the male nozzle. In this case, the penetrating end of the male nozzle only contacts the gasket on a part of its periphery. The gasket is then gradually compressed, as the male nozzle progresses through the female nozzle, over only a part of its periphery. This reduces the maximum insertion force by spreading its application, necessary for compressing the gasket, over an extended insertion length.
- In the solution proposed in this document, the recess in the female nozzle has a bottom, a first side wall formed by the circular section of the retaining ring and a second side wall formed by an internal shoulder of the tubular body. The side walls are facing each other and the recess has a section essentially in the shape of a parallelogram. The essentially constant distance between the two side walls is greater than the diameter of the O-ring so that it can fit freely in the recess.
- When the male nozzle is inserted into the female nozzle, it contacts a part of the gasket and tends to push it against the side wall formed by the internal shoulder of the hollow body before compressing it at the bottom of the recess. When pushing the gasket back into the recess, it tends to twist, making it more difficult to compress. The insertion forces applied to the male nozzle are still relatively high.
- The present disclosure aims to overcome all or part of the drawbacks of the prior art. In particular, it aims at providing a female nozzle of a connection enabling the insertion of a male nozzle with a reduced force.
- In order to achieve this goal, a female nozzle of a connection is disclosed, comprising:
-
- a tubular main body defining a main axis of insertion and having one connection end adapted to receive a male nozzle;
- one retaining ring inserted into the main body on the connection end side, with the retaining ring having a circular section;
- one internal annular recess having a bottom, a first and a second side wall, with the bottom and the first wall being defined by an internal shoulder of the main body and the second wall being defined by the circular section of the retaining ring, with the annular recess not being contained in a transversal plane, which is perpendicular to the main axis of insertion; and
- a sealing gasket positioned in the annular recess.
- The first and second side walls of the female connection are oriented toward the bottom of the annular recess, so that the latter has a trapezoidal section configured so as to clamp and retain the sealing gasket.
- By thus trapping the gasket in the annular recess, its movement at the bottom of the recess and its twisting when inserting the male nozzle is prevented. The insertion force is therefore moderate, and is not affected by the twisting of the gasket. In addition, the trapezoidal shape of the recess gives it a sufficient volume to accommodate the gasket material when it is compressed by the male nozzle.
- According to other advantageous and non-limiting characteristics of the disclosure, taken either separately or in any technically feasible combination:
-
- the bottom of the annular recess may have a dimension larger than the diameter of a segment of the gasket;
- the retaining ring may have at least one alignment pin configured so as to be accommodated in one alignment recess provided on the main body;
- the retaining ring may include at least one notch provided in one opening of the main body so as to keep the ring clamped in the main body;
- the female nozzle may include a clip engaged as a jumper into recesses of the retaining ring and the main body positioned opposite one another;
- the retaining ring may include a first segment having an outer diameter greater than the outer diameter of a second segment so that a peripheral section of the first segment of the retaining ring positioned against a bearing shoulder of the main body is exposed.
- Other characteristics and advantages of embodiments of the present disclosure will emerge from the detailed description of non-limiting example embodiments presented below with referring to the appended drawings, in which:
-
FIG. 1 shows an exploded view of a female nozzle according to the present disclosure; -
FIG. 2 shows a cross-sectional view of a female nozzle according to the present disclosure in an assembled, functional configuration; -
FIG. 3 is a graph illustrating a non-limiting example of the variation in distance between the center of an annular recess within a female nozzle in accordance with embodiments of the present disclosure, and a transverse reference plane, as a function of circumferential position around the annular recess through 360° of rotation. - The
female nozzle 1 includes of a tubularmain body 2, shown here as being angled in the non-limiting embodiment illustrated inFIG. 1 . Themain body 2 has aconnection end 2 a for receiving the end of a male nozzle, not shown in the figures. The tubularmain body 2 defines a main axis along which the male nozzle may be inserted. - The
female nozzle 1 also includes aretaining ring 3, the outer diameter of which is adjusted to the inner diameter of theconnection end 2 a of themain body 2 so that it can be accommodated therein.Alignment pins 3 a make it possible for thering 3 to be inserted into themain body 2 at a given angular orientation by sliding intoalignment recesses 2 b provided on themain body 2. Twonotches 3 b formed on the outer periphery of thering 3 are provided to fit intoopenings 2 c provided on theconnection end 2 a of themain body 2 and to maintain thering 3 clipped into themain body 2. - The
female nozzle 1 also includes an O-ring gasket 4, which is retained in themain body 2 by thering 3. - When the
ring 3 is inserted into themain body 2 in the assembled, functional configuration of thefemale nozzle 1, twoclip recesses 3 c arranged on thering 3 and diametrically opposite each other are respectively arranged so as to correspond to two and align withother clip recesses 2 d provided on themain body 2. Ajumper clip 5, which can be metallic, can be inserted into theclip recesses ring 3 on themain body 2. - However, embodiments of the present disclosure are by no means limited to the features for fixing the
ring 3 to themain body 2 just described, and any other means for retaining thering 3 on themain body 2 may be considered as a replacement for, or in addition to those presented. -
FIG. 2 shows that thegasket 4 resides in an internalannular recess 6 of thefemale nozzle 1 that is not contained in a transverse plane, i.e., in a plane perpendicular to the main insertion axis of the male nozzle. In other words, thegasket 4 and the internalannular recess 6 of the female nozzle are not planar in the assembled, functional configuration. In this way, the penetrating end of the male nozzle comes into contact with the O-ring gasket 4 over only a part of its periphery. This part tends to increase as the male connection progresses. As a result, thegasket 4 is gradually compressed, thus reducing the maximum insertion force required compared to the case where the gasket is planar and entirely located in a transverse plane perpendicular to the main axis along which the male nozzle may be inserted. - In the example shown, the
annular recess 6 has a “wavy” shape, i.e., the distance between the center of theannular recess 6 and a transverse reference plane (e.g., located at the opening of thefemale nozzle 1 as shown inFIG. 2 ) varies in the form of a sine wave with the radial orientation. The solid line inFIG. 3 thus illustrates the variation in distance between the center of anannular recess 6 within afemale nozzle 1 and a transverse reference plane (which can be arbitrarily defined as any plane that is perpendicular to the main axis along which the male nozzle may be inserted, as a function of circumferential position around theannular recess 6 through 360° of rotation. By thus modulating the distance from the center of theannular recess 6 to a reference plane with such radial orientation, it is ensured that thegasket 4 does not reside in a planar, transverse plane. Of course, embodiments of the disclosure are not limited to the particular “wavy” shape represented byFIG. 3 , and any other shape that distorts thegasket 4 to place it outside a transverse plane may be appropriate. This could be, for example, the shape shown as a dotted line inFIG. 3 . - In the example shown in
FIGS. 1 and 2 , the retainingring 3 comprises a first straight segment, i.e., with a constant length, and asecond section 3 d the length of which varies with the radial orientation, for example according to the developed shape shown as a solid line inFIG. 3 . The first section has a larger outer diameter than the outer diameter of thesecond section 3 d. This difference in diameter exposes a peripheral edge of the first section of the retainingring 3 that can be placed against a bearingshoulder 2 e of themain body 2. This makes it easier to position thering 3 in themain body 2 and to insert themetal jumper clip 5 into the jumper clip recesses. - As clearly visible on the insert in
FIG. 2 , the internalannular recess 6 is defined by a bottom 6 a and twoside walls recess 6 a. Thebody 2 has ashoulder 2 f defining the bottom 6 a and afirst side wall 6 b of theannular recess 6. The circular section of the retainingring 3, and more precisely the circular section of the second segment of this ring, defines thesecond side wall 6 c of therecess 6 a. - The sections of the retaining
ring 3 and theshoulder 2 f do not reside in a transverse plane, but are inclined toward this plane to face the bottom of therecess 6 a. Thus, theannular recess 6 has a trapezoidal section, with the large base of the trapezoid being the bottom 6 a of theannular recess 6. The small base of the trapezoid is defined by the smallest distance between the circular section of thering 3 and theshoulder 2 f of themain body 2. - According to embodiments of the disclosure, this small base is chosen to be smaller than or equal to the diameter of a section of the O-
ring gasket 4 in its free-standing state, i.e., when it is not deformed by compression. In this way, thegasket 4 is clamped and retained between the section of the retainingring 3 and theshoulder 2 f of themain body 2. It is therefore not likely to be displaced from theannular recess 6. By thus trapping thegasket 4 in theannular recess 6, movement and twisting of thegasket 4 is prevented when inserting the male nozzle. This feature ensures that the insertion force of the male nozzle remains low. - To facilitate the compression of the
gasket 4, and to contribute to a minimum insertion force of the male nozzle, the size of the large recess base 6 (the bottom 6 a) is advantageously chosen so that it is larger than the diameter of a section of the O-ring gasket 4 in its free-standing state. This creates a space in theannular recess 6 making it possible to accommodate the material thegasket 4 is made of, when it is compressed and deformed by the male nozzle as it progresses into the female nozzle. - Of course, the invention is not limited to the described example embodiments and alternative solutions can be used without departing from the scope of the invention, as defined in the claims.
